FOUNTAIN-LAMP.

Specification of Letters Patent No. 15,198, dated June 24, 1856.

To all whom it may concern:

Be it known that I, NICHOLAS LINDEN, of Jersey City, in the county ofHudson and State of New Jersey, have invented a new and usefulImprovement in Fountain- Lamps; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,in which Figure 1, is a vertical section of my improvement, the plane ofsection being through the center. Fig. 2, is a vertical section of thefountain, the plane of section being indicated by (m), (m), Fig. 1.

This invention relates to an improvement in the style of lamps which areprovided with a reservoir for holding the oil the reservoir beingconnected by a tube with the wick cylinder or tube.

The invention consists in the peculiar construction of the reservoirwhereby the necessary vacuum is readily obtained over the oil within thereservoir so as to insure an equal or regular supply of oil to the wickas will be hereinafter shown and described.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A, represents the wick tube or cylinder which contains the wick B. Thistube or cylinder is constructed in the usual way and therefore does notrequire a minute description.

C, represents the reservoir for holding the oil. This reservoir isformed of two cylinders D, E, one placed within the other. The innercylinder E, has a shaft (a), passing through its center, the end of theshaft working in the sides of the cylinder D. The cylinder E, is allowedto rotate within the cylinder D, and has an opening (6), made throughits edge over which opening a valve (0), is placed said valve beingwithin the cylinder E, and attached tosprings or elastic rods (01),(cl), the ends of which are curved and project through the opening (5).The springs or rods (cl), (d), keep the valve (0), over the opening (6),when they are acted upon by inclined projections. These inclinedprojections designated by (e), (e), are placed on the inner side of thecylinder end of the shaft passing through the outer cylinder as shown inFig. 1.

The reservoir is filled by turning the inner cylinder E, by means of thearm or handle G, till the opening (6), in said cylinder is directlyunderneath the opening (f), in the outer cylinder. The cylinder E, isthen filled with oil by pouring it through the openings (6), the valve(0), being open in consequence of the upper projection (e), bearingdownward the springs or rods (d), When the cylinder E, is filled or thenecessary quantity poured in it, the cylinder E, is turned till theopening (6), is brought over the orifice of the tube F, the valve atthis point being opened by the lower projection (e), and the oil passesdown into the wick tube A.

The valve (0), it will be understood is closed when the rods or springsare not acted upon by the projections (e) (e).

The oil is prevented from being forced up too rapidly in the wick tubein consequence of the vacuous space which is formed as the oildiminishes in the cylinder E.

The fountains in present use are formed by placing one box withinanother and the fountain is filled by entirely removing the inner boxinverting it and pouring the oil through a valve in its bottom the innerbox when filled being placed within the outer one and the valve raisedby a pin in the bottom of the outer box. The objection to the ordinaryarrangement is, that the process of filling the reservoir is adisagreeable one, a person has his hands and often his clothes soiledwith oil; and in furnished apartments, the carpets, upholstery, etc.,are liable to be greased.

By my improvement the reservoir may be readily filled and without dangerof spilling the oils or greasing the hands or clothes.

Having thus described my invention What the projections (e), (e), on theinner side of I claim as new and desire to secure by Letthe cylinder D,substantially as described for 10 ters Patent, is the purpose specified.

Constructin the reservoir C of two cylinders D, E, oiie placed withinthe other the NICHOLAS LINDEN inner cylinder E, being provided With aWitnesses: valve (0), attached to springs (61), (d), said JAMES F.BUCKLEY, valve being opened at the proper points by WM. TUSOH.
